AAppinafion ined May 25, 1917. serial 110.170,86?.

The Vpresent improvements,y relating as in-v i l dicated to oiling systems, are more particularly concerned with the provision ofl 'an economical and Simple device for furnishingV lubricant to any desiredchamber or reservoir in amounts suificient to maintain practically a constant'supply therein at jall times.

` `My invention has, as a V'furthergobjecn the j other mechanism for refillingand as read-Y' provision of a systemin Awhich the'lubricant container may be readily removed r'from Ythe A ily replaced when filled, the container being inthe crankcase and it is desirable that the.

preferably provided with means -fwhich render 'it' possible to handleY it without spilling. vVVhile obviously *applicable to many different mechanisms the present invention'is believed to be particularly useful in connection with an internal combustion engine in a motor vehicle `for maintaining a constant s upply'of lubricant in the' crankcase. Itis essential that a certain level be. maintained `v lubricant does'not exceeda certain -levelorV smokinghof thezmotor andthe' deposit of carbon'will result. lThe presentinvention avoids both difficulties by the Ymaintenance y of apredetermined supply in the crankcase which cannot be exceeded or diminishedvexcept by'a negligible amount while the yreservoir is filled. Y a

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawingand the following description set forth in detail certain mechanism embodying the invention, Such disclosed means constituting, however, but one of various mechanical forms in'which the principle of the invention may be used.

In said annexed drawing Figure l is an elevation showing my improved invention as applied to a crank-case of an internal combustion engine; Fig. -2 is a central-vertical section through'the remov- Patented JAug. 24, 1920.' l

able oil container; and Fig. 3 is a Similar" view but showing a cap on the container.

' In Fig. 1I have-'shown a crank-case l of an internal Vcombustion engine, into which' lthere extends rav lubricant supplying conduit 2. Adjacent to the end of the conduit 2 is ay recess or pocket 3 adapted to collect dirt and dust which will otherwise enter the crankcase with the oil. To the left ofthe pocket 3 the conduit 2 is branched land the two branch conduits 4 and 5 are extended upwardly into a casing 6, which may kbe mounted at any convenient place adjacent to the engine, and if usedon a vehicle,'pr`eferably on the dash or instrument board. The

conduit 4 terminates at a -suitable height in Athe casing 6, while the conduit 5 is extended upwardly a considerable distance beyond the top of this'chamber.' Thepoint 'at which the conduit 2 is branched isbelowthe level that is desired to be maintained in the crankcase, tliislevel being indicated by the VVline 7.

' Removably mounted in the casing 6 in'an inverted position is a bottle-shaped casingV f for lubricant, which is .adapted to bel positionedover the extension. ofthe conduit 5,l

and to be supported on' a suitable collar or other support 9, formed about the opening into the casing 6. The Ylower end or mouth of the bottle-shaped container VEll is adapted tobe a slight distance below the top of the conduit Ll.

The operation of the device 'is as fol-V lows The container. 8v isirstyilled with lubricant and then'po'sitioned as shown in Fig. l overthe extension'of the tube 5 and mounted in the neck 9 in the casing 6. In this position the-lubricant from the casing 8 will flow into the casing 6 until it reaches the level of the top of the conduit 2l, whenit will How down through this conduit into the crank-case of the engine until the level of the oil in this crank-case has reached the top of the conduit 2. As soon as this level is reached no more air from the crank-case can pass up'through the air conduit 5 into the top of the container 8. Aas more oil flows down from the latter into the casing 6 and then through the tube 4 in the crank-case a partial vacuum is formed above the oil in the container 8, and this vacuum will very soon prevent the further flow of liquid from this container into the casing 6. The flow of oil from the casing 6 into the tube 4 will from the casing 6 into the tube 4, but the y amount will not be sucient to lower the level in the casing 6 more than a fraction of an inch below the top oi the tube-4. i

When the oil in the crank-case has been used until its level is below the end of the tube 2 air .will pass through this tubel into.

the vtube 5 and from there into the tube of the container `8. ln this way the vacuum existing in the top of Vthis container will be filled and the oil in the container 8 will then iow by gravity to the mouth of thecontainer into the casing and then down to the Ytube 4 in the crank-case until the end of the tube 2 is again covered bytheoil in the rfhis filling action will be re-, peated automatically whenever the level ofv crank-case.

the oil in the crank-case drops below the end of the tube 2 and no attention is required to secure this operation.

provided with a tapered outlet 11` which will 'be normally closedwhen the casing i'sV inverted-by means of a simpleball valve 12.

By the use of this or an equivalent construc-v tion the casing S may be invertedfor positioning inthe casing 6 without the loss of any oil.

8 is inserted over the tube 5 the beveled end 13 of the latter will push the ball 12 to one side and will thus open the mouth of the bottle around the tube to permit the lubricant to flow down into the casing 6.

F or convenience, threading 14 may be formed on the neck of the container 8 to receive a cap 15 which will serve toseal the container when not in use, and if' desired similar threading may be formed on the neck 9 so that the container may bep'os'if` tively engaged therewith it is believed that a resilient bracket 16 will be sufficient; for this purpose, the bracket being mounted on the dash or instrument board, ii the mechanism is used on a vehicle.

When the mouth of the bottlev Other modes of applying the 'principle of my invention may be employed instead of the one explained, change-beingmade as regards the 4mechanismY herein disclosed, provided the means stated by any or" the following claims or the equivalent of such stated means be employed.

Itherefore particularly point out'and distinctly claim as my invention 1. The combination with an oil reservoir., of a conduit leading thereto at the level to be maintained therein, a holder mounted adjacentto the upper open end of said conduit, and a normally sealedgcontainer adapted, when set in said holder 'andpositioned over the open end of said conduit to automatically be placed in connection tlierewitli,'said container being provided withmeans adapted to seal the same upon normal removal froxnsaid conduit. Y l.

2. The` combination with an soil reservoir, of a-conduit leading thereto at the level to be maintained therein, and extending vertically upward therefrom, s aid conduit havinga beveled upper open end, a' lubricant holder mounted adjacent such open end of said conduit, and ailubrioantY container having. a single openinga.valve normally clos ing suclropening, said container being adapted tobe inserted in said holder with suchopen end of said conduit inserted in such opening,r said beveled conduit being adapted to displace said valve 'and open said container into saidconduit.
